How the fuck are you going to tame all these 6'5" giant "milfs", with gigantic tits, gigantic asses, and gigantic hips and... tiny midriff for some braindead reason... with a little dick.
I really, really don't want to, but if shorter than women MC for no reason is supposed to be fucking giants, then he has to be equipped to fuck giants.
Until male MC is 10% taller than these "milfs", I couldn't possibly give less of a shit.
Rendering realistic intercourse is more work, so stuffing a big one in there renders the other half of the equation inert.
So this is relevant.
Ideals are a good thing, if people are thinking straight anyways.
Vaginal physiology is relevant.
Male physiology and erectile dysfunction is also relevant.
